One can define a simple theory where baryon number is a local symmetry spontaneously broken at the low scale [1]}, [2]}, [3]}, [4]}, [5]}.
In Ref. [2]} it was shown that using vector-like quarks one can cancel all baryonic anomalies.
The fermions needed for anomaly cancellation and their quantum numbers under the new gauge group
\(SU(3)_C \otimes SU(2)_L \otimes U(1)_Y \otimes U(1)_B\)
